Abstract
Description
본 발명은 엘씨디 모듈에 관한 것으로, 더욱 상세하게는 탑샤시와 미들 샤시의 조립 강성을 증대시켜 탑샤시의 들뜸을 방지한 엘씨디 모듈에 관한 것이다.The present invention relates to an LCD module, and more particularly, to an LCD module that prevents lifting of the top chassis by increasing the assembly rigidity of the top chassis and the middle chassis.
최근들어 전자손목시계로부터 컴퓨터의 모니터, 대형 전광판에 이르기까지 자기장에 의하여 배열이 바뀌어 광이 통과/차단되는 성질을 적극적으로 이용한 LCD의 개발이 꾸준히 진행되다.Recently, the development of LCD which actively uses the property of passing / blocking the light by changing the arrangement by the magnetic field from the electronic watch to the computer monitor and the large electronic display is progressing steadily.
최근에는 차량에 장착되어 텔레비젼을 시청할 수 있도록 차량용 LCD 모듈까지 개발 보급되고 있다.Recently, a vehicle LCD module has been developed and distributed so that a TV can be mounted on a vehicle.
특히, 차량에 장착되는 LCD 모듈의 경우 일반 랩탑형 컴퓨터, 가전제품에 적용된 LCD 모듈에 비하여 충격 진동이 많이 전달되게 된다.In particular, in the case of the LCD module mounted on a vehicle, shock vibrations are transmitted much more than LCD modules applied to general laptop computers and home appliances.
이와 같이 주변으로부터 전달되는 충격 및 진동에 견디도록 하기 위해서 차량등 이동수단에 장착되는 LCD 모듈은 백라이트 어셈블리에 LCD 패널을 올려놓은 후 탑샤시를 조립하는데 이때 탑 샤시는 백라이트 어셈블리로부터 돌출된 턱부위에 걸은 상태에서 탑 샤시를 회전시켜 백라이트 어셈블리의 상면에 안착시킨 후 탑 샤시에 형성된 고정 부재를 변형하여 백라이트 어셈블리와 탑샤시는 고정된다.In order to withstand the shock and vibration transmitted from the surroundings, the LCD module mounted on the vehicle, such as a vehicle, puts the LCD panel on the backlight assembly and assembles the top chassis. After the top chassis is rotated and seated on the top surface of the backlight assembly in a hanging state, the fixing member formed on the top chassis is deformed to fix the backlight assembly and the top chassis.
이 조립구조의 하단부로부터는 패널의 플랙시블 프린티드 서킷(FPC)가 돌출되어 인쇄회로기판과 연결되고 탑 샤시의 하단부의 플랜지는 넓게 형성되어 FPC를 보호하는 기능이 있어 외력에 의한 변형은 쉽게 발생하지 않는다.The flexible printed circuit (FPC) of the panel protrudes from the lower end of the assembly structure to connect with the printed circuit board, and the flange of the lower part of the top chassis is formed wide to protect the FPC. I never do that.
그러나, 상단부는 LCD 패널의 위치고정을 위하여 탑샤시 상단부의 플랜지는 좁아지게 되어 외력이 가해지거나 자체의 조립 응력이 조금만 가해져도 변형이 발생되기 쉬운 구조로 되어 있어, 탑 샤시와 LCD 패널이 일정한 간격을 유지하지 못하고 탑 샤시의 상단 중앙부가 들뜨는 현상이 발생하여 외관불량이 발생하는 문제점이 있다.However, in order to fix the position of the LCD panel, the upper part of the top chassis has a narrow flange, which is easy to be deformed even when external force is applied or its own assembly stress is applied. There is a problem in that the appearance of the top center portion of the top chassis is not lifted to maintain the appearance defect.
따라서 본 발명은 이와 같은 종래 문제점을 감안한 것으로써 본 발명의 목적은 탑 샤시의 들뜸 현상을 방지함에 있다.Accordingly, the present invention has been made in view of such a conventional problem, and an object of the present invention is to prevent the lifting phenomenon of the top chassis.
도 1은 본 발명에 의한 엘씨디 모듈의 부분 분해 사시도.1 is a partially exploded perspective view of an LCD module according to the present invention.
도 2는 본 발명에 의한 엘씨디 모듈의 일부분을 확대 도시한 사시도.Figure 2 is an enlarged perspective view of a portion of the LCD module according to the present invention.
이와 같은 본 발명의 목적을 달성하기 위한 LCD 모듈은 백라이트 어셈블리와, 백라이트 어셈블리의 상면에 안착된 LCD 패널과, LCD 패널의 위치를 고정시키는 가이드 패널이 고정시키는 미들샤시와, 미들샤시에 형성된 걸립홈에 결합되어 상기 미들샤시와의 들뜸을 방지하도록 고정쇠가 적어도 1 개소 이상 설치된 탑 샤시를 포함하는 것을 특징으로 한다.The LCD module for achieving the object of the present invention comprises a backlight assembly, an LCD panel seated on the upper surface of the backlight assembly, a middle chassis fixed by the guide panel for fixing the position of the LCD panel, and a gripping groove formed in the middle chassis. Coupled to and characterized in that it comprises a top chassis installed at least one or more fasteners to prevent lifting with the middle chassis.
이하, 본 발명에 의한 LCD 모듈을 첨부된 도면을 참조하여 설명하면 다음과 같다.Hereinafter, the LCD module according to the present invention will be described with reference to the accompanying drawings.
백 라이트 어셈블리에 LCD 패널을 올려놓은 다음 탑샤시(10)를 조립하게 되는데 탑 샤시(10)는 탑 샤시(10)의 상단쪽에 설치되어 있는 갈고리 형상의 걸림턱을 미들 샤시의 걸림부재에 걸고 반대편 하단쪽은 회전하여 탑 샤시(10)는 백 라이트 어셈블리(20)의 상면에 안착되고 탑 샤시(10)의 양쪽 측면에 있는 고정쇠(15)를 걸림턱(25) 방향으로 변형시켜 탑샤시를 고정시킨다.The LCD panel is placed on the backlight assembly, and then the top chassis 10 is assembled. The top chassis 10 hangs the hook-shaped hooking jaw installed at the upper side of the top chassis 10 to the middle member, and the other side is hooked. The lower side is rotated so that the top chassis 10 is seated on the upper surface of the backlight assembly 20 and the top chassis 10 is fixed to the latching jaw 25 by deforming the fasteners 15 on both sides of the top chassis 10 to fix the top chassis. Let's do it.
이러한 조립구조의 하단부는 LCD 패널의 FPC가 나와 뒤쪽으로 인쇄회로기판과 연결되어 있어 탑 샤시(10)의 하단부가 플랜지를 넓게 하여 FPC를 보호하는 기능을 가지고 있어 외력에 의한 변형이 쉽게 되지 않으나, 상단부는 LCD 패널의 위치 고정을 위한 가이드 패널이 있고 이를 고정하는 미들 샤시가 몰드의 안쪽으로 밀착되면서 고정하게 되어 있다.Since the lower part of the assembly structure is connected to the printed circuit board to the rear of the LCD panel FPC, the lower part of the top chassis 10 has a function to protect the FPC by widening the flange, so that deformation by external force is not easy. The upper part has a guide panel for fixing the position of the LCD panel, and the middle chassis fixing the LCD panel is fixed to the inside of the mold.
이때, 탑 샤시(10)의 상단부에 있는 갈고리형상의 고정쇠(15)가 미들 샤시의 걸림턱(25)에 걸리게 되기 때문에 탑샤시가 외부로 들뜨는 현상을 방지할 수 있다.At this time, since the hook-shaped fastener 15 in the upper end of the top chassis 10 is caught by the locking jaw 25 of the middle chassis, the phenomenon that the top chassis is lifted to the outside can be prevented.
이상에서 살펴본 바와 같이 외력이 가해지거나 자체의 조립 응력이 가해져도 변형이 발생하지 않음으로써 탑 샤시와 LCD 패널이 일정한 간격을 유지하게 되어 외관 불량에 대한 문제점이 해결되는 효과가 있다.As described above, even when external force is applied or self-assembly stress is applied, deformation does not occur, thereby maintaining a constant distance between the top chassis and the LCD panel, thereby solving the problem of appearance defects.
